Diesel exhaust harmful to health and climate!
§ Globally, diesel vehicles produce 90
percent of PM and 95 percent of BC
emissions (ICCT Health Roadmap)!
§ One kg of black carbon causes as much
climate impact in the near term as 3,200
kg of carbon dioxide (Forster, et al.)!
§ BC is the second largest contributor to
climate warming from human activities
(Bond, et al.)!

16. Impact of fuel sulfur!
§ Diesel fuel quality!
§ 15 ppm required for Tier 2 and beyond diesel
vehicles.!
§ Higher sulfur will increase emissions rapidly and
could damage vehicle.!
§ Gasoline fuel quality!
§ 30 average / 80 maximum for Tier 2!
§ 10 average / 80 maximum for Tier 3!
§ Sulfur locks up the precious metal sites on the
catalyst, reducing catalyst efficiency. Important
benefits from better catalysts even with higher sulfur
fuels.!
§ Impacts of higher sulfur fuels are completely
reversible. Possible to phase in cleaner fuels and
vehicles at the same time.!

17. Fundamentals of controlling air pollutant emissions
from motor vehicles!
New vehicle standards!
!
Must consider emissions from
all mobile sources: on-road, off-road,
marine, locomotives,
aviation, construction…!
!
Limit values only as good as:!
- Compliance and enforcement!
- Real-world performance!
!
Fuel quality standards!
!
High fuel quality (especially
low sulfur levels) enables
advanced emission control
technologies to be deployed
in the fleet.!
!
Fuel quality compliance
programs critical to prevent
damage to engines and
prevent misfueling!
!
!
In-use vehicle emission
control!
Measures include:!
- Catching gross-emitters (I/M,
remote sensing, maintenance)
- Cleaner fuels!
- Fleet renewal!
- Retrofit programs!
- Complementary strategies
(low emission zones, driver
training, etc.)!
“Systems Approach”!
